i with these Objects in View the invention- `will-"behereinafterdescribed an consistsfin ythe construction, arrangement, and combinationof the several arts, all as afterward pointed out in the claims. 'j-

Suitable' bracketsentend from-the side walls'and" rovide bear' s ofa `,shaft.id/anat .oneend ofwhicl is'arranged-a andwheel 5.- 'The shaft-'4" instead 'ofv beingpro-4 l vided withstand-wheel may have a, squared -end.,portiontorpermit the'use'of a wrench,

. v 1 1 repre? sents rock-arms fixed to shaft 10, which rock# armsia're'conne ctedf,I to 12,' which `'carry at'their. oppositejends a shaftg13,there v'Patented June 19', 1906,v

preferably being ashaft 13 under each door. he. ends of shaft 13 carryrollers 14, which'` coperate with inclined tracks 15, supported 55 fromtheside walls and center sills of the car, respectively, saidtracks 1 5bein preferably inclined, as shownin Fig. 3, the 'ghestporf tionsof eachtr ck also having a horizontal portion onwhich theroller' 14 rests whenthe 6o door is closed. ShaftsI 13 also carryrollers "16, Whichicoperatewithflanged lates 17,-

depending from the doors 18,l t e lower flanges o said platesconstituting bearing-f surfaces for coperatingA with the rollers 16. 65:Whenthe doors are closed, the rollers .16 lie under the flat portionsof the bearing-surfaces, which flat portions are substantiallyparallelto the Ado'oranels., The bearingsurfacerecedes towar lthe hingededge of the. 7o

door, so as tocoperate with rollers 16 'when' the rollers 14 are movedalong the tracks to permit the door to open, as shown dotted lines inFig. 3.

To open the doors, it is only necessaryl to 75 i i `raise the pawl andoperate thehand-wheel so as to cause the rollers 16 to travel from the.position shown .in-full lines in Fig. 3 to the po-. sition shown indotted lines in said Jligure,

when the weight of the door will cause the 8ovv door-to drop to theposition shown'in dotted lines, inwhich position therollers 16 are attheir eXtreme lower limit of movement. To close the doors, the directionof movement of the hand-wheel 'is'reversed, causing the roll- A85 l ers14 to move 1n an opposite direction on their tracks, in. which 'eventthe rollers -16 will ride under the inclined surfaces of the plates 17until the doors areclosed, the iinal movement causing the rollers 16 -tobe lo-go cated well'under the horizontal portions of said bearin-surfaces and also upon the 'hori- 'l zontal 4portion of thetrack 15,in'which posi? tion .therollers 1.6 are at the extremity of theirclosing.mo'ven'ienuc Due to the fact 95 that in operation therollcrs 14and 16 rotate in; opposite directions one or'vboth sets should i p beloo's'e on the shaft 13.1 Y

7 While i have `shown the-mechanism as apr plied to two doors, it:is-obvious that a greater `I oo number of 4doors could. be operatedh'om the same'poweri-shafttfas, for instance, the l. car wasprevided'with four doors the powrl shaft.' could` bev located betweentwo j transverseiy-arranged 'iairs ci doers. The object of gearing downrorn the shaft 4 is to multi'p, y the power derived from the hand-Wheel5.

ain aware that minor changes in the construction, arrangement, andcombination of the several parts ci my device can be made andsubstituted ier those shown and described without departing from thenature and principie of my invention.

.Having thus described the invention, what is claimed as new, anddesired to be secured by Letters Patent, is;- l

infin a car-doorepeiating mechanism, the combination with doors locatedcn opposite sides of the center sills oi the car, of a shaft extendingacross lthe car and provided with sets of rock-arms, links connected tosaid rock-arms, a reciprocating shaft mounted in the opposite ends ofeach set of links, tracks cooperating with the ends oisaid reciprocatingshaft, rollers on said reciprocatin shaft cooperating with said doors,gearing ocated between the center sills of the car 'for drivin the shaftwhich carries the rock-arms, an

seance means extending to one side of the car for o eratin said gearing;substantially as escribe 2. 'in a car-door-operatin mechanism, thecombination of al -drivingaft 4 having a pinion mounted thereon, ashaft10 havin a ear-wheel 9 meshing with the pinion onda e :st-mentionedshaft, rock-arms on the shaft 10, links 12 connected to said rock-arms,a shaft 13 mounted in the` ends of links 12, roll,- ers 14 on the endsof shaft 13, tracks 15 with which saidrollers cooperate, rollers 16carried by the shafts 13, and a hinged door provided with abearing-surface 17 for coperating with said rollers 16; substantially asdescribed.

, In testimony whereof I hereunto affix my signature, in the presence oftwo Witnesses, this 29th day of December, 1905.
